Solution plasma synthesis of Pt/ZnO/KB for photo-assisted electro-oxidation of methanol

Facile synthesis of Pt nanoparticles supported on anatase TiO2 nanotubes with good photo-electrocatalysis performance for methanol

“…And the size of as-prepared Pt nanoparticles is approximately 2-5 nm, on the basis of our previous TEM measurements. 55,61 Fig. S2 † shows the XRD patterns of two Ti foils, which were directly obtained aer the rst anodization step and obtained aer annealing process, respectively.…”

“…53 In this present work, the free-standing TiO 2 nanotubes were synthesized by a simple two-step anodization method with titanium metal foils and NH 4 F in ethylene glycol. A simple, high-yield and rinsing-free method, preparation of Pt nanoparticles with plasma sputtering in water, [54][55][56][57][58] was used. The electrochemical results indicated that TiO 2 nanotubes supporting Pt catalysts (Pt/C/TNTs) expressed a promoted activity toward methanol electro-oxidation under light illumination.…”

Enhanced Electrocatalytic Oxidation of Methanol on Pt‐Decorated Bi2WO6/Graphene Nanosheets with Visible Light Assistance

“…On the contrary, the chronoamperometry is also a crucial approach in determining the long-term stability of the catalysts. [34,35] As shown in Figure 7A, the initial current densities decreased promptly, which is ascribed to the undesirable formation of intermediate poisoning substance (e.g., CO ads ) and the reduction of catalytic active site. As time passed, the current densities decreased slightly and tended to be stable.…”

Recent Progress on Photo‐Promoted Alcohol Electrooxidation for Fuel Cells

“…[ 39 ] A composite of Pt/ZnO nanowire/KB was also reported that the peak current density (≈964 mA mg −1 Pt ) of Pt/ZnO/KB‐1 is over twice than that in dark (≈432 mA mg −1 Pt ) when light irradiation is supplied during cyclic voltammetry testing. [ 40 ] It should be mentioned that possibly due to the different power densities of light sources, ZnO nanorod arrays in the former case are shown to be active while the ZnO nanowires in the latter work exhibit no photo‐promoted activity for methanol.…”
